R211x-HP Flexfabric 11900 Security Command Reference

233
The keepalive timeout time configured at the local must be longer than the keepalive interval configured
at the peer. Because more than three consecutive packets are rarely lost on a network, you can set the
keepalive timeout timer to three times as long as the keepalive interval.
Examples
# Set the keepalive interval to 200 seconds
<Sysname> system-view
[Sysname] ike keepalive interval 200
Related commands

Parameters
seconds: Specifies the number of seconds between IKE keepalives. The value is in the range of 20 to
28800.
Usage guidelines
If the local end receives no keepalive packets from the peer during the timeout time, the IKE SA is deleted
along with the IPsec SAs it negotiated.
The keepalive timeout time configured at the local end must be longer than the keepalive interval
configured at the peer. Since more than three consecutive packets are rarely lost on a network, you can
set the keepalive timeout timer to three times as long as the keepalive interval.
